#11 Fix mistakes in BOM and/or footprints

[bjohan]

Update the BOM to refer to the correct components.
Current mistakes that should be changed:

• The capacitors in the MOD_OUT filter (C8, C6, C4, C3) should be 0603 not 1206
• C11, C7 and C5 are the same component, should have identical footprints.
• The uln2003 should use a footprint with wider padsto make it easier to solder.
